HOSE-COUPLING.

Specification of Letters Patent.

Patented July 3, 1906.

Application led September 30, 1904. Serial No. 226,642.

To all whom it may concern.-

Be it known that I, JOHN H. STEPHENS, a citizen of the United States,residing at Vernon, in the county of Wilbarger and State of Texas, haveinvented new and useful Improvements in Hose-Couplings, of which thefollowing is a specification.

This invention has reference to improvements in hose-couplings; and itconsists of'certain novel features of construction, whichwill be fullydescribed in the specification, elucidated in the drawings, and clearlypointed out in the claims.

The object of this invention is to provide a hose-coupling that will besimple in its construction, durable and practical in all 'its parts,whereby an inexperienced person can manipulate it and make attachmentswithout any instructions.

The invention is so constructed and arranged that an ordinary personwithout any mechanical ability can connect the two ends of a broken orruptured hose by screwing the same on the screw-threaded inclinedmembers through the medium of small bars, which are secured in a ring orwasher centrally located between the opposing ends of saidscrew-threaded members. This washer is conical or flared on its internalperiphery, so as to force and bend the hose ends firmly against theconical or flared surface of said washer. The hose ends are clamped andfirmly secured on their respective inclined members by two opposingsleeves, one sleeve enveloping its adjacent sleeve throu h the medium ofscrew-threads on both s eeves, whereby turning the larger sleeve thefree ends of the hose are firmly clamped and held in position. Thetapering screw-threaded members have slots formed diametrically oppositeeach other and extending a part way into said members for small bars toenter for turning said members. There is also a mortise on oppositesides of one of the members for allowin a spring-catch to play andprevent the was er from becoming,y detached when the hose is uncoupled.

Figure 1 is a vertical longitudinal section of the improved hose-couplinWith a portion in elevation. Fig. 2 is an e evation of the device as itwould appear when in practical operation. Fig. 3 is a lon itudinalsection of one of the inclined screw-t readed members. Fig. 4 is anelevationof one of the inclined screw-threaded members. Fig. 5 is afront view of one of the members. Fig. 6 is a vertical section of thelarger sleeve. Fig. 7 is a similar view of the smaller sleeve. Fig. 8 isa section of the flared Washer with the bars in elevation. Fig. 9 is anelevation of the iiared washer, artly broken away to exhibit the methodof) securing one of the springcatches. Fig. 10 is an elevation of theflared washer with the bars removed. Fig. 11 is a4 section through oneof the screwthreaded members, exhibiting the recesses on thescrew-threads. Fig. 12 is a vertical lon itudinal section of thehose-coupling wit the washer centrally located between the hose endssomewhat modified.

The invention consists of two inclined screw-threaded members 1 and 2,respectively. These members have interposed between them a washer 3.Said washer carries two bars 6 6. The free ends of said bars 6 enterslots formed in the ends of said inclined screw-threaded members 1 and2. Enveloping the screw-threaded members are hose ends 18. Said hoseends extend over and beyond said members and are drawn inwardly over theends of said members by means of the iiared washer 8. Embracing theoutside of the hose ends are sleeves 12 and 20, which have inclinedsurfaces 14, so as to fit snugly on the hose ends. These sleeves areprovided with screw-threads 15 and 16 for drawing the hose ends togetherthrough the medium of the inclined screw-threaded members. Thescrew-threaded member 1 is also provided with mortises C C for allowingthe free ends of spring-catches 8 to play therein. These spring-catchesare secured by screws 10 to bars 6 6. (See Fig. 9.) The catch portion 9enters said mortises C. The ends of the bars 6 are cut away, as shown at7 for allowing the springs 8 to be depressed when entering the mouth ofthe screwthreaded member 1. The screw-threads A on the inclined membersare of peculiar construction. They are inclined, as shown at b, and havea shoulder a., which is approximately vertical for the purpose ofpreventing the hose from slipping off of the inclined members.Equidistant around the screwthreads A are recesses E for preventing thehose from becoming unscrewed, as hose will unscrew itself when twistingit around. The ends of the screw-threaded members are in i IOO clined,as at G, for allowing the curved hose members 1 and 2 until the inclinededges of ends 19 to rest thereon and become parallel the screw-driverwedge within the slots B,

with the inclined or flared periphery 5 of the washer 3. This washer hasdovetailed slots 4 4 for receiving the bars 6 previously referred to.The sleeves 12 and 20 are inclined on their rear portions, as indicatedat 11 11, and their opposite ends are provided with hexagon nuts 17,which are integral with said sleeves. Sleeve 2O is provided with anannular rib 21 (see Fig. 7) for centering the washer 3 when assemblingthe coupling, otherwise undue strain would come on the bars 6 and bendthem.

In Fig. 1 a portion of the hose on the righthand member is shown inelevation for exhibiting the slot 22, a number of them being formed atthe hose ends, especially when large hose are employed, but for ordinarygarden-hose the ends can remain perfect at their ends, as the resilienceoi the rubber will accommodate the inclined screw-threaded members 1 and2, respectively. When the coupling is disassembled, the washer 3 remainsin the screw-threaded member 1 by means of the spring-catches 8, as thecatch 9 impinges on the walls of the mortises C when said washer isresting loosely within said member 1.

In Fig. 12 the same construction is shown as that in Fig. 1, with theexception of the ends of the hose being square and a plain.

Washer 3A being employed. This washer can be made of any suitablematerial-rubber, or indurated fiber, or metal.

When assembling the improved hose-coupling, the hose ends 18 are screwedon the inoline of the threaded member 1 or 2, and the sharp portions aof the screw-threads are embedded into the rubber of the hose; also therecesses E come into play at this stage of assembling, as the hosecannot become unscrewed, as the soft material enters these recesses andiiils it in a measure. When one of the hose ends is screwed completelyon the member 1 or 2, the other member is then screwed on its member 1or 2; but in screwing the hose ends on said members said members must beheld iirmly. rThis is accomplished by the bars 6 6, which are located inthe slots B of both members, which act as a screw-driver. After the hoseends contact the inclined or liared washer 3y then the sleeves 12 and 20are employed for drawing the parts irmly together, thus forcing the endsof the hose in the position, as shown at 19, against the face of theiiared washer aforesaid. It will be observed that the mortises C are ofsufficient size to allow the members to be drawn closely together, asfar as it is possible, for the purpose in view. The bars 6 6 can bedispensed with and an ordinary screwdriver can be inserted within thebore of the when it can be turned for the purpose of securing themembers 1 and 2 of the hose ends, respectively.

Having described the invention, that which I desire to secure by LettersPatent of the United States is 1.
